Review Summary

5 Reviews

this product was terrific.

Nice and light. Kept me toasty warm. Perfect jacket for an outdoor adventure! [This review was collected as part of a promotion.]

Love it

Now that I got the correct size , absolutely love it. It really does react and keeps me warm for such a light jacket. Mine in blue, ran very large. Usually a true small in Under Armour but had to send back and get xs. 110lbs, 5 ft tall.

Love it

I absolutely love this coat just like I thought I would. So cute and comfy.

WOW! This coat is super light and compact and awesome.

I didn't expect it to be very warm because it's just so light. I wore it on my morning dog walk (so, not a lot of warmth created/slow walking) and it was about 34 degrees. I wore a long sleeve base layer and really didn't think it would be enough. It was amazing! I was perfectly comfortable, not too hot and not cold at all. I did a lot of standing around and maintained a constant level of comfort. I'm a size 4 and got a size sm/p but I did have to have it altered a bit. The sleeve are wide and long but my tailor did a great job is sizing it for me. I'm so glad I kept this as I can tell it's going to be a really versatile piece. It packs up quite small so great for taking on trails for the 'just in case I get cold' piece. This jacket is great value and I highly recommend it.

Great Jacket

I received this jacket and love it. Unfortunately it was a bit big on me so I have to exchange it for a smaller size. Normally the reviews are really great to help me assess what size I need but there weren't any for this item. I normally wear Small or even Medium and the description said this jacket was fitted however, I will need to go down a size so would say it runs on the larger end. I am very excited to be able to wear this jacket in the fall and winter. It is very light, comfortable and the magnetic zipper is great! I also did not know that the whole jacket can fit into a little pouch that serves as an inside pocket when you wear it. I would definitely recommend this jacket and look forward to wearing it!
